PORTABLE NIICROSCOPE AND CASE THEREFOR- SPECIFIGATION forming part of Letters Patent No. 752,889, dated February 23, 1904.

Application tiled December 22, 1903. Serial No. 186,157. (No model.)

vTo a/ZZ whom it may concern:

taining boXes or cases in which the instrument with its heavy metal base is placed; but the box is large, cumbersome, and heavy in itself, and with the complete microscope and the usual accessories is so heavy and bulky that the physician or microscopist will not carry his instrument with him when he otherwise would in order to save time and work under the most favorable conditions. It has also been proposed to provide a traveling-case Jfor microscopes having a hinged lid on which the stand is secured in operative position and which serves as the base for the instrument. This construction is objectionable, because the accessories are contained in the case and the cover must be opened and the adjustments of the instrument destroyed each time a new device is to be used.

The primary object of the present invention is to produce a full-sized portable microscope and containing-case for the same and the usual accessories which is light, compact, and of attractive appearance, and in which the case affords a stable convenient base for the instrument. p

Other objects of the invention are to improve the construction of the microscope and its case in several particulars, which will appear from the following description.

'In the accompanying drawings, Figure 1 is an end elevation of a containing-case embodying the invention. Fig. 2 is a longitudinal section of the case, showing the microscope in front elevation in place therein. Fig. 3 is a plan view of the case, showing the same open and the microscope therein. Fig. 4 is a vertical section of the body of the case, showing the microscope therein, partly in elevation 'and microscope.

partly in section. tion of the case-cover, showing the same inverted and constituting the base of the microscope. Fig. 6 is an elevation of the body of the case, showing the hinges in section. Fig. 7 is a side elevation of the microscope-in operative position on the cover-base. Fig. 8 is a fragmentary vertical sectional elevation, on

and B, which constitute, respectively, the

body and cover of the base and are preferably made of metal covered with leather or the Fig. 5 is a transverse seclike material c to give the case the necessary strength and stiffness without unduly increasing its size and to lend a neat attractive appearance resembling a traveling case or bag. The body and cover are connected by suitable hinges D, a catch e and lock f of any suitable form being employed to hold the cover closed.

The hinges connecting the body and cover are of a construction permitting the cover to be detached from the body and inverted to form the base of the microscope, as hereinafter described. The hinges shown consist of hingelugs al, secured to the back of the body and provided with pintles al', and hinge-lugs d2, securedto the back of the cover and having holes to receive the pintles on the other lugs.

The hinge-lugs on the body project above or beyond the edge of the back, while the hingelugs on the cover are arranged iiush with the edge of the back or set in the back, so that when the latter is detached and inverted the edges of its ends and sides will rest fiat uponA a table or supporting-surface and will not rock or be unsteady. The edge of the back of the cover is provided adjacent to its hingelugs with recesses olto receive the hinge-lugs z hung on said pivot.

of the body when the cover is closed, so that a tight joint is eifected between the body and` con/struction', except as hereinafter-explained,

and comprises a stand Gr, tube g, hinged thereto for inclining the stage g', substage g2, carrying the usual illuminating apparatus, preferably constructed and arranged as described in, United States'Letters Patent No. 700,409,

granted to me May 20, 1902, and mirror g3.

A The stage is pivoted to the stand, so that it can be turned from the operative position shown in Fig. 7 to the position shown in Fig. 3, in which it is parallel with the plane of the stand, to permit it to be placed in the case.v This pivotal connection is preferably constructed as follows, (see Figs. 8 to'l0:) .The stand is provided at the front of its lower end with a fiat vertical face L,-to which is secured a forwardly-projecting screw Zt',- constituting a pivot, and the stage is provided with a depending pivot plate'or arm 712, having a hole through whichk the pivot passes. The pivot-arm of the stage is pressed against the front-face stand to take up any looseness f by av spring-washer 7b3, surrounding the pivot between the pivot-arm of the stage and the swinging arm if for the mirror, which is also z', Figs. 9 and l0, is a stop-pin which proi' 'jects from the rear face of the pivot-arm of the stage into a circular groove in the front face of thetube-arm and is adapted to engage coperating stationary stops Z 2 to arrest the stage in its operative and folded positions.

4The stage is held rigid in its operative position by a clamping-bolt K passing horizontally through a hole in the stand and having at its front end a head c, engaging in` an undercut open-ended Icurved slot lo', formed in lthe rear face of the pivot-arm ofthe stage concentrically with the stage-pivot. The rear end of the bolt-shank is threaded and provided with a thumb-nut k2, by turning which the bolt can be drawn inwardly to'l clamp and A hold the stage.

763 is a spring coiled about the clampingbolt in a recess in the stand between the rear endofv the recess and a pin or shoulder la* on the bolt. This spring acts to project the clamping-bolt forwardly when the thumb-nut is loosened, so that its head will slide freely in its slot and will enter the open end thereof without striking the walls of the slot.

The cover of the case is detached from the body and inverted, as shown in Figs. 5 and 7 when used as the base of the microscope, which is detachably secured in an upright po- 'end of the bolt-hole.

sition on the cover-base, preferably by vthe following means:'

L represents a securing-bolt located in a longitudinal hole Z in the lower end of the stand and having a projecting headedend,

which is adapted to enter a keyhole-slot Z', formed externally in a socket-plate Z2, secured centrally on the case-cover in any suitable' mannen jected, so as to readily enter the keyhole-slot by a spring Z5 between its inner end and the The bolt serves to hold its operating-'shaft in place. The case-cover affords a rm,,stable^ base for the microscope, and as the latter is secured on the outside of the cover it is elevated sufficiently above the supporting table or surface and enables the instrument to be used with convenience.

rlhe body of the case is provided with holding devices for the various accessories of the microscope-for instanc'eM represents a rack, secured at the back of the body near one end, and is provided with retaining-holes m for the eyepieces and objectives, which are held in the rack by a padded plate or bar N, slidably mounted on liXedv pins n at the back of the cover and held in yielding engagement with the parts in the rack by springs n', surrounding the pins n. As the cover is detached from the body of the case when using the instrument, the body, which contains the microscope accessories, can be placed in a convenient position near the instrument and the accessories taken therefrom as required without disturbing the position or adjustments of the microscope, which is a great advantage of a construction in which the part of the case forming the base of the microscope i's not detached roo IIO

from the other part and must be moved each time a device is taken from the case.

1f desired, a separate tripod or base (not shown) can be furnished with the instrument for use in the laboratory. Such base is provided with a socket similar to that on the casecover for the engagement of the securing-bolt. It will be understood that this supplemental base is not carried about with the instrument in the case. n

When the vmicroscope is to be placed in the case, the mirror is detached from its swinging arm and the stage with the attached substage is turned to the position shown in Figs. 2 and 3, in which it is parallelv with the stand. In

this position the stage occupies much less space transversely of the instrument than When it is in operative position, and the instrument can consequently be inclosed in a case considerably narrower than the Width of the stage.

The body of the case is provided at one end (see Fig. 3) with a plate O, having an undercut slot p, in which the head of the base-securing bolt is engaged in placing the microscope in the case to hold the microscope from movement in the'case in the position shown in Fig. 3.

I claim as my inventionl. A microscope case or receptacle comprising detachably connected sections, one of which constitutes a base for the microscope and is provided with means for securing the microscope thereto, substantially as set forth.

2. A microscope case or receptacle comprising sections, hinges detachably connecting said sections, one of said sections .constituting a base for the microscope, and having means for securing the microscope thereto, substantially as set forth.

3. A microscope case or receptacle comprising detachably connected sections, one of which when detached and inverted constitutes a base for the said section having external means for securing the microscope therein, substantially as set forth.

4. A microscope case or receptacle comprising detachable hinged sections, the hinge members in one section being set into one side thereof, whereby said sections will rest firmly in asupporting-surface when inverted to form a base for the microscope, substantially as set forth.

5. Amicroscope case or receptacle comprising detachable hinged sections, one of said sections having hinge members set into one side thereof, and recesses adjacent to said hinge members, and the other section having projecting hinge members adapted to enter the recesses in the other section when the sections are closed to prevent the detachment of the sections except when opened, substantially as set forth.

6. The combination of a microscope, a case therefor, a device for securing the microscope in operative position on said'case comprising cooperating parts on the microscope and case,

- and a part in said case Which cooperates with said securing part on the microscope to hold the latter from movement in the case, substantially as set forth.

The combination of a microscope, a case therefor provided with a socket, a bolt on the microscope which cooperates with said socket to hold the microscope in operative position in the case, and a socket in the case with which said bolt coperates to hold the microscope stationary in the case, substantially as set forth.

8. The combination of a microscope, a case therefor provided with a socket-plate externally slotted, a bolt on the microscope which engages in said slot to hold the microscope in operative position on the case, and a slotted plate in said case in which said bolt engages to hold the microscope stationary in the case, substantially as set forth.

9. The combination of a stand, a stage provided on said stand and provided with an undercut curved slot concentric with the stagepivot, and a clamping-bolt mounted in said stand and having a head which enters the curved slot in the stage, substantially as set forth. A

10. The combination of a stand, a stage provided With an arm pivoted on said stand, and provided Withan undercut curved slot concentric With the stage-pivot, cooperating stops on saidstage arm and stand to limit the pivotal movement of the stage, and a clampingbolt mounted in said stand and having a head which engages the curved slot in the stage, substantially as set forth.
